Electric dragonfly
Dragonfly is one of the fastest and most perfect flying insects. It is able to accelerate to 50 km / h, remain motionless in the air and maneuver with accelerations up to 9g. It was the dragonfly that served as the prototype for the four-winged TechJet robot. Electric dragonfly fits easily on the palm and weighs only 25 grams.
One of the main differences between TechJet Dragonfly from small radio-controlled helicopters and quadrotors is the ability to plan, saving energy. A lithium-polymer battery of 250 mAh is enough for 10 minutes of flight in the hang mode, but in the hybrid mode the dragonfly can hold out in the air for up to 25-30 minutes. And this is not the only advantage - one of the models, according to the assurances of developers, is able to fly almost silently.
Mobile wings can easily fold or even detach, allowing you to carry the dragonfly, even in your pocket. You can manage it over WiFi, using a regular tablet or smartphone.

Order one or more dragonflies on the crowdfunding site IndieGoGo , the first deliveries are scheduled for July 2013. This project compares favorably with many of these flying toys on an unusually serious foundation. This is not just a toy, TechJet expects that the "dragonfly" will be used in military, police, rescue operations, video surveillance and aerial photography. Development of "Dragonfly" began on the order of the US Air Force - the project team received a grant of one million dollars.
TechJet Dragonfly - not a cheap hack from standard components. Avionics, mechanics, wings - everything was created from scratch, taking into account the unusual style of flight. TechJet already has five patents for various dragonfly nodes. In retail, the younger dragonfly model will cost from $ 250, IndieGoGo prices are several times lower, but the lots are rapidly ending - the stated campaign target of $ 110,000 has already been exceeded by one and a half times.
